As a standardized NGN architecture, the 3rd generation partnership project IP multimedia subsystem (IMS) defines standard service capabilities and interfaces, as well as a common IP-based infrastructure, which enable operators to introduce new services in an efficient and flexible way. In order to exploit the capabilities offered by an IMS operator, multimedia application developers face a business challenge to create applications which can run on a variety of user devices, and possibly adapt to various network conditions and user preferences. Our goal was to identify common generic functionality related to session-level QoS signaling for advanced multimedia applications and to design a high-level application programming interface (API), which invokes this functionality. The paper describes the dynamic service adaptation model on which the proposed API is based, the API specification, and its implementation in Java. A prototype multimedia application featuring a 3D networked game provides an example of using the API
When lambda expressions were introduced to the Java programming language as part of the release of Java 8 in 2014, they were the language’s first step into functional programming. Since lambda expressions are still r...

The widespread use of smart contracts results in high repeatability of their source code. The solution seems to lay in reusing the verification rules that check the feasibility of logically related transactions. The software allows for developing a smart contract that may process various transaction types. Besides, employing the package in implementing a smart contract eliminates the redundancy of verification rules. The package structure ensures the ability to handle actual smart contracts and transactions at the abstract level. Moreover, the article presents a proposal to standardize the way of designing the transaction verification function in a smart contract.

We describe the use and distributed implementation of a functional language based on the graph‐reduction concept. Attention is given to the issue of implementing higher‐order functions and concurrent evaluation. Prospects for optimization of this implementation are pointed out.
